I have plaque psoriasis all over my arms and some on my legs, have tried all manner of cures and creams, including sterioids, to no avail. Recently bought a tube of a cream called Sorion on Amazon, and it's working - patches much paler and scales gone. It contains coconut oil, neem, and turmeric as well as titanium dioxide, it also has BHA in which I think is basically salycilic acid. It did sting a bit for the first few days but not any more. I'm really happy as I haven't worn short sleeved shirts in years. I have no financial interest in this company, just sharing in hopes it will help others.
